I think if you've accepted Jesus, and you're contributing in some way to help others find him, then he would be happy for you that you have a BMW.

After all, the gifts used to create a great car like a BMW were given to those engineers and designers by God. Them using those gifts are beautiful in God's eyes. God finds great joy when we use the gifts that he has given us, he just asks that we thank him when we do.

Do you talk to God? Does he answers? Serious questions, really.
I mean, you base your life on a book and a prayer, so communication with God might be something we can capture on audio tape. Thanks in advance.
